Lord Sugar says Van Gaal must resign, and criticises Manchester United fans

Former Tottenham Hotspur chairman Lord Sugar has been ruthless in his assessment of Manchester United's boss.

Former Tottenham chairman Lord Sugar has criticised Manchester United boss Louis van Gaal in the wake of the club's defeat to Arsenal.

United were knocked out of the FA Cup by a home quarter-final loss to the Gunners, with Van Gaal making his fair share of questionable decisions.

The Dutchman left Radamel Falcao as an unused substitute, and brought off Ander Herrera at half-time, while his choice to sell Danny Welbeck to Arsenal last year came back to haunt him as the England striker scored the winner.

Lord Sugar, famed in recent years for his 'You're Fired' catchphrase on television show The Apprentice, used his Twitter page to call for the manager to leave United.

United had lost only two of 22 previous games heading into the game, but have now seen their only remaining chance to win a trophy disappear.

Next up are Tottenham Hotspur, who they face in the Premier League at the weekend, with a three point gap between the two teams.

Sugar was also critical of the United fans who chose to boo striker Danny Welbeck when he was substituted after hitting the winner. Welbeck chose to celebrate the goal despite making his name at the Red Devils and coming through their academy.
